To all whom it may concern:

My invention relates to that class of sup-' ports for an electric lightto which the lamp may be rigidly secured or supported, as by means ofwires; and'the object of myi-nvention is to provide a device of thisclass that shall be extremely durable and 'efiicient and one consistingof a small number of parts' which may be economicallyconstructed. A

form of structure .in the use of which these objects may be attained isillustrated in the accompanying drawings, in which- Figure 1 is a viewin central section through a rosette embodying my'invention. Fig. 2 isa-bottom View of thecap. I Fig. 3 is a plan view of the base. Fig.' 4:is a perspective view showing the construction of the contacts. Fig. 5is a plan view of the base, showing another form of embodiment of theFig. 6 is a view in side elevation, showing means for rigidly connectingthe lamp with the base. Fig. 7 is a perspective view showing thecontacts embodied in the structure of Figs. 5 and 6. In the'accompanyingdrawings the numeral v 1 denotes the base of the structure, having a lthe base to secure the conductor in place.

clamp-screw 8 is employed for securing the chamber 2 and recesses 3located in the bottom of the chamber. Openings 4: are formed throughthebottom of thebase, and grooves 5 extend from each of these openingsto the recesses in the bottom of the base provided for the reception ofcontact members. Each of these contacts is constructed from a singlepiece of metal first cut to proper shape to produce the final form,whichis obtained by bending the parts to the form shown in'the lowerdevice of Fig. 4. Each contact consists of a foot 6, Which is engaged bya screw 7, projecting through the bottom of A end of the li'ne wire. Abranch 9 extends upward from the foot, and its upper portion is bentinward, forming a part 10. Abranch 1 Specification of Letters' Patent.Application filedDecember'b, 1902. Serial No. 134,133.

11 extends upward from the opposite side of the foot, its upper endalso-being curved ins ward and forming a contact 12, overlying thecontact 10. Itis to be noted that the contact members of the base haveall except their cesses 3, and, as hereinafter described, when the capis in place these contacts are entirely isolatedone from the other intheir individual chambers,

The cap 12 has a central opening 13 for the reception of thela'mp-wires.The cap is provided with central projections 14 to protect the severalparts through which the electricity travels. "1 1 of the cap areprovided with recesses in which the contact members 15 are located, andas the projecting insulation extends beyond the contact members Whenthecap is in place with reference to the base isolated chambers are formed,partially in the cap and partially in the base,-'within which thecooperating contacts of the base and cap are completely inclosed andisolated one from the other. Contact members 15 are secured to the cap,as by means of screw 16, and clampscrews 17 areemployed for attachingthe lamp-wires to each contact member. Each of the contact members isprovided with an offset portion 18, forming a contact. It will be notedthat these contact members are located in recesses in the cap, thelamp-wires being led through grooves into these recesses in whichthe'conductors are located, so that there is little danger in attaching thecapto the base that parts not so intended can touch and 7 the contactmembersecured to the base 19 is formed in two parts and projects throughthe wall 20 outside of the central recess in the base. The foot 21 ofthe contact member bears a binding-screw 22 for securing the line wiresin place. The contact is formed of a forming a lip 24:, and a branchextends up-' ward from the opposite side and is bent inward, forming alip or contact 23., The attaching-screw 25, which passes upward It is tobe noted that the projectionsthrough the bottom of the base, also passesupper extremity entirely inclosed in the reeach other, and thusshort-circuit the device. I I

-' In the form of device shown in Figs. 5, 6,

singlepiece of metal having a branch extend mg upwardfrom one side andbent inward, 1

J 1 Is through the bottom of the contactand through the foot 21 into thelip 24, thus securing the parts in position. A contact 26 is secured tothe cap and is similar in construction to that described with referenceto Figs. 1, 2, 8, and 4, the engagement of the cap with the base beingformed in the same manner. While the description has been confined to asingle contact on the cap and on the base, it will be understood thatthere are a plural number of such devices on each of the parts.

The cap 27 may be provided on its outer surface with a recess 28, inwhich a lampsocket 29 may be located, the screws 30 in this instance,which bind the two portions of the lamp-socket together, extending intothe cap to unite the socket thereto and also engaging the contacts 26,if desired, for the purpose of holding the latter in place. The screws30 also secure the contacts and bearing-plates 31 in position.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. A base of insulating material, contacts secured to the base, eachincluding a foot, an arm extending upward from the foot and having itsend bent at an angle to the main part and forming a cooperating contact,and a second arm extending upward from the same base and having its bentend overlying said first-named contact part, all of the several partsformed from a single piece of material bent to shape, a cap, andcontacts arranged thereon each provided with an end adapted to enterbetween the contacts of the base and be clamped thereby.

2. A base of insulating material, contact devices mounted therein eachconsisting of a base, an arm projecting upward from one side of the basewith its end bent to form the contacting surface. an arm projectingupward from the opposite side of the same base, with its bent endoverlying said contacting part, the several parts formed from a singlepiece of material bent to shape, a cap, and contacts borne by the capeach having an end adapted to enter between the ends of the contact onthe base and cooperating therewith to hold the base and cap securelytogether.

3. A base of insulating material, a contact consisting of a foot havingmeans for attachment of a line-wire, arms extending upward from oppositesides of the foot, each having bent ends one overlying the other andparallel with relation to each other, one of said arms having a partprojecting into the space between the parallel overlying ends andforming a detent for a cooperating contact member, a'cap, and contactsarranged upon the cap and adapted to enter between the ends of thecontact on the base, and be engaged and held by the said base-contacts.

4:. A base, contacts secured to the base each including a foot, armsprojecting upward therefrom and with their ends bent the one overlyingthe other, the several parts formed from a single piece of material bentto shape, a cap, contacts secured to the cap each having an end adaptedto enter between the ends of the contact on the base, and means forsecuring the wires to said parts.

A base having contacts, said base having a peripheral flangeextending above the contacts, a cap having a central projection,extending within and meeting the base, and provided with a centralopening, wire-clamps located in recesses formed in the periphery of andon diametrically opposite sides of the projection, grooves from thecentral opening through the body of the projection into said recesses,contacts located as to their body parts in recesses formed in the bodyof, and on diametrically opposite sides of said cap projection, saidcontacts having their contacting ends projecting beyond the capprojection, and arranged to engage the contacts of the base, andconnections between the clamps and contacts.

8. In combination in arosette, abuse of insulating material havingdepressed recesses to receive contacts whereby the contacts are isolatedand insulated one from the other, contacts arranged in said depressedrecesses, a cap bearing cooperating contact members, the latter arrangedwithin depressions in the cap and an integral boss projecting from thecap about and beyond the contacts and engaging the base and cooperatingtherewith to form isolated chambers for each of the contact members whenin engagement.

9. A base of insulating material having contact-recesses at its bottom,and provided with an outer rim extending above the contacts carriedtherein, recesses formed in the inner wall of said rim, and joining thecontact-recesses at the base, base-contacts located in thebase-recesses, and with contacting parts projecting upward along thewall-re cesses, a caphaving a central boss fitting within the rim ofthebase, and projecting to the bottom thereof, contact-recesses formed insaid boss, grooves and a central opening connecting wlthsald recesses,and contacts having their body part located in the recesses
